Hi there. I've been trying to solve some lockups and pauses wi=
th my system and
have just read this entire thread.=20
The good news is that I am another Radeon VII owner having the same problems
and I am willing to do whatever I can to help.
My current situation is:-
- I'm running dual 2560x1440@60Hz via display port.
- I am running the beta of ubuntu 19:10 (Linux ryzen1910 5.3.0-18-generic
#19-Ubuntu SMP Tue Oct 8 20:14:06 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux).
- I don't push the R:VII at all under Linux. I boot into Windows 10 to play
games.
- I have disabled IOMMU in BIOS/EFI. With IOMMU enabled things are MUCH wor=
se.
- My system is mostly stable. If the displays blank, sometimes after waking
them I get the 15-30 second freeze. Then the "amdgpu [powerplay] Faile=
d..."
messages and then everything continues ok. I can semi-reliably recreate thi=
s by
using the "xset dpms force off" command someone posted earlier. I=
've not
managed to find any kind of pattern yet, but 8 out of 10 times running that
command and then waking the system with a keypress/mouse click will cause t=
he
freeze.
- I use X11 and not wayland. Not sure that is significant, but with Ubuntu
19:10 it seems wayland is started temporarily and then stopped during boot /
starting gdm. If I enable IOMMU my GDM login screen will be completely corr=
upt.
However, if I press enter (to select my user) and enter my password, my X11
gnome session starts. Although there are LOTS of pauses and warnings and er=
rors
all over the place in "journalctl -f".
